<p>PROBLEM TO BE SOLVED: To provide a heat insulation material capable of being fitted to a frame space without any gap.SOLUTION: A heat insulation material 1 is constituted of two foam heat insulation panels 10, 10 which are an extrusion-foamed material and are laminated so that the respective extrusion directions are identical with each other. The two foam heat insulation panels 10, 10 have an identical dimension between edges in a direction perpendicular to the extrusion direction, and are firmly bonded being displaced each other in the extrusion direction.</p> |
